Hydroprocessing of hydrocarbons over nickel, moly, platinum catalyst

Abstract

A process for hydrotreating (hydroprocessing) hydrocarbons and mixtures of hydrocarbons utilizing a catalytic composite comprising a combination of a nickel component, a molybdenum component and a platinum component with a zeolitic carrier material wherein said platinum component is present in an amount sufficient to result in the composite containing, on an elemental basis, about 0.2 to about 0.5 percent by weight platinum, in which process there is effected a chemical consumption of hydrogen. Hydrocarbon hydroprocesses are hydrocracking, the hydrogenation of aromatic nuclei, the ring-opening of cyclic hydrocarbons, desulfurization, denitrification, hydrogenation, etc.

       2. The process of claim 1 further characterized in that said conditions include a pressure of from 400 to about 5000 psig., a liquid hourly space velocity of from about 0.1 to about 10, a hydrogen circulation rate of from 1,000 to about 50,000 scf./bbl. and a maximum catalyst temperature of from about 200° F. to about 900° F. 
     
     
       3. The process of claim 1 further characterized in that said catalytic composite contains from about 1% to about 15% by weight of said nickel component and from about 1% to about 10% by weight of said molybdenum component, on an elemental basis. 
     
     
       4. The process of claim 1 further characterized in that said catalytic composite contains from about 0.1% to about 1.5% by weight of a halogen component, on an elemental basis. 
     
     
       5. A hydrocarbon hydroprocess which comprises reacting a hydrocarbon with hydrogen at conditions selected to effect chemical consumption of hydrogen, and in contact with a catalytic composite of a platinum component, a nickel component, a molybdenum component and a zeolitic carrier material; said process further characterized in that said catalytic composite is reduced and sulfided prior to contacting said hydrocarbon. 
     
     
       6. The process of claim 5 further characterized in that said zeolitic carrier material is a faujasite. 
     
     
       7. The process of claim 5 further characterized in that said zeolitic carrier material is admixed with an amorphous refractory inorganic oxide. 
     
     
       8. A process for desulfurizing a sulfurous hydrocarbon distillate containing mono-olefinic hydrocarbons and aromatics, which process comprises reacting said distillate with hydrogen, in contact with a catalytic composite comprising a combination of a nickel component, a molybdenum component and a platinum component with a zeolitic carrier material wherein said platinum component is present in an amount sufficient to result in the composite containing, on an elemental basis, about 0.2 to about 0.5 percent by weight platinum. 
     
     
       9. A process for hydrogenating a coke-forming hydrocarbon distillate containing di-olefinic and mono-olefinic hydrocarbons, and aromatics, which process comprises reacting said distillate with hydrogen, at a temperature below about 500° F., in contact with a catalytic composite comprising a combination of a nickel component, a molybdenum component, a platinum component and an alkali metal component with a zeolitic carrier material wherein said platinum component is present in an amount sufficient to result in the composite containing on an elemental basis, about 0.2 to about 0.5 percent by weight platinum, and recovering an aromatic/mono-olefinic hydrocarbon concentrate substantially free from conjugated di-olefinic hydrocarbons. 
     
     
       10. A process for improving the jet fuel characteristics of a sulfurous kerosene boiling range fraction, which process comprises reacting said kerosene fraction and hydrogen, at a maximum catalyst temperature below about 750° F., in a catalytic reaction zone containing a catalytic composite comprising a combination of a nickel component, a molybdenum component and a platinum component with a zeolitic carrier material wherein said platinum component is present in an amount sufficient to result in the composite containing, on an elemental basis, about 0.2 to about 0.5 percent by weight platinum, and separating the resulting reaction zone effluent to recover a normally liquid kerosene fraction having improved jet fuel characteristics.
